A gravure printing press assembly composed of an impression roller having a core portion, a support shaft for the core portion which is rotatable with respect to the core portion, and an outer conductive layer disposed about the core portion and a high-voltage contact assembly for applying a high voltage to the impression roller. The high-voltage contact assembly comprises a first assembly having a brush support member and a plurality of brushes associated with the brush support member, the brushes being held by the brush support member at a plurality of positions circumferentially disposed with respect to a central axis passing through the support shaft; a second assembly having a conductive contact ring disposed adjacent the brushes and being rotatable relative to the first assembly; and means for allowing relative movement between the first assembly and the second assembly in a direction parallel to the central axis of the support shaft.

Presse d'héliogravure composée d'un rouleau d'impression muni d'une partie centrale, d'un arbre de soutien pour la partie centrale qui peut tourner autour de la partie centrale, d'une couche extérieure conductrice placée autour de la partie centrale et d'un élément de contact de haute tension pour exercer une haute tension sur le rouleau d'impression. L'élément de contact de haute tension comprend une première partie dotée d'un élément de soutien de balais et de plusieurs balais fixés à l'élément de soutien de balais, ces derniers étant retenus par l'élément de soutien des balais à plusieurs positions disposées en circonférence par rapport à l'axe central passant à travers l'arbre de soutien; une deuxième partie dotée d'un anneau de contact conducteur placé à côté des balais et rotative par rapport à la première partie; et des dispositifs pour permettre un mouvement relatif entre la première partie et la deuxième partie dans une direction parallèle à l'axe central de l'arbre de soutien.
